Problems solved by technology

The addition of fragmented carriers will bring about an increase in the total number of PRBs, resulting in the situation that the RBGs corresponding to the number of PRBs of backward compatible carriers, fragmented carriers, and aggregated carriers are different, that is, UEs of lower versions and configured with fragmented carriers The RBG size determined by the UE in the new version based on the number of PRBs is inconsistent
Since existing standards do not support resource allocation for two or more UEs with different RBG sizes at the same time, after configuring the sliced ​​carrier, you will face the problem of how to determine the RBG size to clearly indicate resource allocation information

Embodiment 1

[0072] In this embodiment, the new version UE aggregation uses a 5MHz backward compatible carrier and a 1.4MHz sliced ​​carrier. When performing resource allocation, the mapping table between carrier bandwidth and RBG size in R8 is used, as shown in Table 1. The RBG size corresponding to the 5MHz backward compatible carrier is 2, and the RBG size corresponding to the 1.4MHz fragmented carrier is 1. According to the division method and numbering method of the present invention: the unified RBG size after aggregation is before and after the fragmented carrier is configured. The RBG size of the compatible carrier, that is, the RBG size corresponding to the 1.4MHz fragmented carrier is also 2;

[0073] After determining the size of the RBG, serially number the RBG of the backward compatible carrier and the RBG of the fragmented carrier, specifically: consider the RB of the backward compatible carrier and the RB of the fragmented carrier as a whole, and divide the RBG according to t...

[0075] In this embodiment, the new version UE aggregation uses a 5MHz backward compatible carrier and a 1.4MHz fragmented carrier; when performing resource allocation, the mapping table between carrier bandwidth and RBG size in R8 is used, as shown in Table 1, The RBG size corresponding to the 5MHz backward compatible carrier is 2, and the RBG size corresponding to the 1.4MHz fragmented carrier is 1. According to the division method and numbering method of the present invention: the unified RBG size after aggregation is before and after the fragmented carrier is configured. The RBG size of the compatible carrier, that is, the RBG size corresponding to the 1.4MHz fragmented carrier is also 2;

[0076] After determining the size of the RBG, serialize the RBG of the backward compatible carrier and the RBG of the fragmented carrier, specifically: regard the RB of the backward compatible carrier and the RB of the fragmented carrier as two parts, and divide them according to the dete...

Embodiment 3

[0078] In this embodiment, the new version UE aggregation uses a 5MHz backward compatible carrier and a 1.4MHz fragmented carrier; when performing resource allocation, the mapping table between carrier bandwidth and RBG size in R8 is used, as shown in Table 1, The RBG size corresponding to the 5MHz backward compatible carrier is 2, and the RBG size corresponding to the 1.4MHz fragmented carrier is 1. According to the division method and numbering method of the present invention: the unified RBG size after aggregation is before and after the fragmented carrier is configured. The RBG size of the compatible carrier, that is, the RBG size corresponding to the 1.4MHz fragmented carrier is also 2;

[0079] After determining the size of the RBG, number the RBG of the backward-compatible carrier and the RBG of the wave-sliced ​​carrier separately, specifically: regard the RB of the backward-compatible carrier and the RB of the segmented carrier as two parts, respectively, according to ...

Abstract

The invention discloses a method for determining a size and a number of a resource block group (RBG) after fragmentation carrier configuration. The method includes that when an enhanced node B (eNB) configures a fragmentation carrier for user equipment (UE), the eNB and the UE determine that the size of the RBG is uniformly equal to a size of a RBG corresponding to a downward compatible carrier which is used by matching with the fragmentation carrier; and according to the determined size of the RBG, a resource block (RB) of the downward compatible carrier and an RB of the fragmentation carrier are treated as a whole or two portions to be subjected to RBG division, and the divided RBG of the downward compatible carrier and the RBG of the fragmentation carrier are numbered. The invention further discloses a device for determining the size and the number of the RBG after the fragmentation carrier configuration. By means of the technical scheme, the fragmentation carrier can be conveniently used by the UE, and when the bandwidth of the fragmentation carrier is small, the influence on a new system can be reduced to the greatest extent.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for determining the size and serial number of RBGs after configuring sliced ​​carriers. Background technique [0002] With the development of the mobile communication industry and the increasing demand for mobile data services, people have higher and higher requirements for the speed and quality of service (QoS, Quality of Service) of mobile communication. Before large-scale commercial use, the research and development work on the next generation mobile communication system has already started, and the typical one is the Long Term Evolution (LTE, Long Term Evolution) project initiated by the 3rd Generation Partnership Project. The highest carrier bandwidth that the LTE system can provide is 20MHz (megahertz). With the further evolution of the network, evolved LTE (LTE-A, LTE-Advanced), as an evolution system of LTE, can provide up to 100MHz carrie...
